Thanks a lot to my friend Michael L Gallagher who supplied our tank tracks from far far away. Now our engineers are able to recreate the tanks in KSP. Panzer 4 is the first recreation of tank and it was a lot of hard work. Seems tank has more complex design than any other armored vehicles therefore it was difficult to make the design close enough with the original design by use of limited stock parts.
The Kerbal foundries mod tracks were a bit small, that's why the first tank is unmanned drone.
The tank's bridge turns 360 degrees
Equipped with 105mm turret (max.pitch 12 / min.pitch -8 / yaw range 2)
You may notice that the turret yawing ability is limited. This will give you a more world war two tankery experience.
The 50.cal front machine gun also has limited yaw.
This Panzer 4 weights 10 tons and able to speed 12.3m/s;
Height 2m, Width 2.9m, Length 6.1m
Good luck!
